We've started to see messages like this on startup: > [2023-07-24 09:16:34,776] WARN Ignoring ambiguous alias 'Value' since it refers to multiple distinct plugins [org.apache.kafka.connect.transforms.HeaderFrom$Value, org.apache.kafka.connect.transforms.ReplaceField$Value, org.apache.kafka.connect.transforms.SetSchemaMetadata$Value, org.apache.kafka.connect.transforms.Cast$Value, org.apache.kafka.connect.runtime.ConnectorConfigTest$AbstractKeyValueTransformation$Value, org.apache.kafka.connect.transforms.ExtractField$Value, org.apache.kafka.connect.transforms.InsertField$Value, org.apache.kafka.connect.transforms.Flatten$Value, org.apache.kafka.connect.transforms.MaskField$Value, org.apache.kafka.connect.transforms.TimestampConverter$Value, org.apache.kafka.connect.transforms.HoistField$Value] (org.apache.kafka.connect.runtime.isolation.PluginUtils:411) This is because `Class::simpleName` doesn't include the names of any outer classes when used on a nested class, and many of the SMTs that we ship out of the box with Kafka Connect use inner classes. For example, the `org.apache.kafka.connect.transforms.ReplaceField` SMT has the inner classes `Key` and `Value`, and the simple name for the `Value` inner class is just `Value` (instead of `ReplaceField$Value` or `ReplaceField.Value`, as one may have expected). We should downgrade to a lower log level since users may think that something is wrong if they start seeing these messages after an upgrade. *More detailed description of your change, if necessary. The PR title and PR message become the squashed commit message, so use a separate comment to ping reviewers.* *Summary of testing strategy (including rationale) for the feature or bug fix. Unit and/or integration tests are expected for any behaviour change and system tests should be considered for larger changes.* ### Committer Checklist (excluded from commit message) - [ ] Verify design and implementation - [ ] Verify test coverage and CI build status - [ ] Verify documentation (including upgrade notes) -- This is an automated message from the Apache Git Service.
